Overview

DevStack has evolved to support a large number of configuration options
and alternative platforms and support services. That evolution has grown
well beyond what was originally intended and the majority of
configuration combinations are rarely, if ever, tested. DevStack is not
a general OpenStack installer and was never meant to be everything to
everyone.

Below is a list of what is specifically is supported (read that as
“tested”) going forward.

The OpenStack Technical Committee (TC) has defined the current CI
strategy to include the latest Ubuntu release and the latest RHEL
release.

Ubuntu: current LTS release plus current development release

Fedora: current release plus previous release

RHEL/CentOS: current major release

Other OS platforms may continue to be included but the maintenance of
those platforms shall not be assumed simply due to their presence.
Having a listed point-of-contact for each additional OS will greatly
increase its chance of being well-maintained.

Patches for Ubuntu and/or Fedora will not be held up due to
side-effects on other OS platforms.

The DevStack exercise scripts are no longer used as integration and gate
testing as that job has transitioned to Tempest. They are still
maintained as a demonstrations of using OpenStack from the command line
and for quick operational testing.
